Many people experience muscle cramps during exercise. Most focus solely on relief methods after symptoms appear, neglecting to understand the underlying causes. Yet identifying the root cause is essential for effective prevention and treatment. So what causes muscle cramps? Why do they occur?
1. Cold Exposure
During winter exercise or swimming, muscles encountering cold stimuli without prior warm-up can undergo forced contractions, leading to cramps.
Therefore, whether in winter or summer, performing a proper warm-up before any activity is essential. This effectively prevents early-stage muscle cramps that could cause injury.
2. Excessive Sweating Causing Muscle Cramps
During exercise (especially in summer), profuse sweating depletes the body's sodium chloride levels. This reduces muscle excitability and disrupts electrolyte balance, triggering muscle cramps.This type of cramping commonly occurs in weightlifting, wrestling, long-distance running, soccer, gymnastics, basketball, and similar activities.
3. Muscle contraction imbalance
During exercise, excessive muscle tension, rapid consecutive contractions, and insufficient relaxation periods can disrupt the coordinated alternation between contraction and relaxation. This imbalance causes muscle contraction irregularities, leading to cramps.For example, this phenomenon can be observed in cycling and sprinting.Fatigued muscles often experience reduced blood circulation and energy metabolism, leading to significant lactic acid buildup. This causes localized muscle tension, obstructing normal blood flow and triggering muscle spasms. Therefore, engaging in strenuous exercise or sudden intense exertion when physically fatigued—especially with localized muscle fatigue—can easily induce muscle spasms.
5. Dietary Principles for Muscle Strengthening
Recommended Foods: Beef, eggs, almonds, black sesame seeds, fennel, amaranth, salmon, corn, oatmeal, apples, oranges, peaches, bananas, fruit juices, various vegetables, legumes, milk, yogurt.
Dietary Recommendations: Increase protein intake.
Dietary Restrictions: Avoid tobacco, alcohol, sweets, and greasy foods.
